1. please quietly copy onto your class notebook
11/23/10 Our Math Goal: To use slope and y-intercept to find the function for any table.
Homework: p.504 #13 to 17
1) Copy and complete the following table, then graph.
2) Look up what the word intersect means.
3) Where does the line intercept the y-axis? x
Function? Y
(x,y) ? 1
(0,1) 3
(1,3) 2 5 7

2. y = slope x y-intercept

3. Classwork Example
Graph the two points onto your graph paper and find the slope and y-intercept of each line. Use them to write the function equation.
Line #1 A(-1,-2) B(2,4)

4. Try on your own
Graph this line onto your graph paper and find the slope and y-intercept of each line.
Write the equation.
Line #2 C(-1,-4) D(3,4)

5. See if you can do this one
Graph this line onto your graph paper and find the slope and y-intercept of each line.
Write the equation.
Line #3 E(-4,2) F(4,6)

6. Self-Test to see if you got it!
Graph this line onto your graph paper and find the slope and y-intercept of each line.
Write the equation.
Line #4 G(-1,5) H(4,-5)

7. Create a graph for the following table, and then use it to find the function equation using slope and
y- intercept x
Equation? y -3 1 -1 2 3

8. Review for HSA: Which of the following best represents the graph of a linear equation that has a slope of 3 and a y-intercept of –2?
A B C D
